The Lethal Swan (also referred to simply as Lethal Swan) was a robot that competed in both series of Dutch Robot Wars. It lost the first round in both of its series appearances, as well as the Losers' Melee in Series 1, effectively losing all three of its battles. Despite its poor success rate, The Lethal Swan became a crowd favourite due to its unique design and flammability, similar to UK Series competitors Nemesis and Diotoir. The audience could be heard chanting "Burn that swan!" during all of the robot's battles.
